Well working at the IU food courts for about a year and a half, I was privy to some of the not-so-tasty secrets of many of their dishes. BUT, one thing that they do VERY well is their garlic knots. It's just like many of you described, pizza dough in a knot, brush salted garlic butter on them and bake. They actually brush more butter butter on midway through the baking process however. Oh, and before I forget, their slated garlic butter contains some dired crushed herbs, and just a little bit of crushed red pepper. The little bit of spice that it adds really makes a difference.
When they are done baking, they are lightly brushed one final time, then heavily dusted with grated parmesan.
SO good, SO easy, SO inexpensive.
